CONTROL CODE FOR ROBOTIC ARMS VIA PC KEYBOARD

CÓDIGO CONTROLE BRAÇOS ROBÓTICOS VIA TECLADO PC

Move, record various positions and watch your robot perform the recorded movements.

Commands through the Arduino IDE's Serial Monitor, see the video above.

Control keys:

Q,A > Move the base (10 degrees and 1 degree in precision mode)

W,S > Move the main arm

L,D > Move the forearm

R,F > Move the grip

G > Record Mode

X, Space > Save a position

P > Play Mode (Perform movements in loop)

CAPS LOCK > If on, enable precision mode

+ , - > Change the movement speed

Warning! ENTER key must be pressed after each command

Supplies

3 Degree of Freedom (DoF) Robotic Arm
Arduino Uno
Mini Protoboard
Power Supply ( 5v/6v - 4A)
Capacitor to reduce servo vibrations (Optional)
Computer with Arduino IDE installed
USB cable
Jumpers

Connections With Arduino

Follow the diagram above for the connections of the robotic arm with the arduino.

IDE Library

Install the VarSpeedServo library in the Arduino IDE.

This library has commands that allow you to regulate the servo drive speed.

Download the library from the link below:

VarSpeedServo

Load the Code

With the external power supply off, upload the code to the Arduino. Then turn on the power supply and open the IDE's Serial Monitor.
